Synonymy The genus has been regarded as a synonym of Polycirrus since at least Saint-Joseph 1894:235 or later Hessle 1917: 226, although it is not clear if these or most subsequent authors have examined the material of type species Polycirrus chilensis. However, Glasby & Hutchings (2014) examined and redescribed the type of P. chilensis, retaining it in Polycirrus. [details]
